2.4" ili9341 help

Post by Spyder » Mon Mar 29, 2021 2:17 pm

I'm working with one of the ili9341 screens with the redboard attached from Amazon
https://www.amazon.com/gp/product/B07KP ... UTF8&psc=1

I've wired it up as follows
SDO (MISO) to pin 21
LED to pin 2
SCK to pin 23
SDI (MOSI) to pin 19
D/C to pin 18
Reset to pin 22
CS to pin 24
GND to pin 20
VCC to pin 17

I left T_IRQ, T_OUT, T_DIN, T_CS, T_CLK, SD_CS, SD_MOSI, SD_MISO, and SD_SCK empty because I don't think I needed them.

Followed Veteran's guide-viewtopic.php?f=43&t=4858&start=120#p72481
And Infiniloop's guide for his GBC (which is literally the same build I'm doing)-https://www.sudomod.com/forum/viewtopic.php?f=43&t=8054
And Infiniloop has been kind enough even to send me his own image and I still only get a white screen.

I'm powering it off of the USB on the pi and have nothing else hooked up to it yet. I'm taking baby steps and getting 1 part working before moving to the next. Wire used is 28AWG magnet wire
Using Retropie 4.3 as well.

Got it working. Cut down the board and soldered magnet wire to the correct pins
